China's international expansion follows multiple paths: trade, investment, finance and currency, to focus on the economy. In doing so, it pursues different objectives.

A review of China's international activity since 2013 is striking first of all by the speed with which it has made China a major player in globalization in terms of both direct investment and lending to developing countries.

The world trading system is facing an existential crisis. This calls for a significant update of the rulebook, dealing with dissatisfactions regarding negotiation and rules, surveillance, as well as adjudication.

The agenda to fix the euro is hampered by conflicting national interests. Creditor countries demand fiscal house cleaning and debtor countries ask for risk sharing. There is currently a political deadlock about how the adjustment burden should be distributed, perpetuating a state of vulnerability that is not in the collective interest of euro area members.
